Migraine Aura after gamma knife

I had gamma knife almost three weeks ago and have experienced migraine Aura without headache(looks like crystal prisms with colored light) with blurry vision lasts 30 to 40 min. I have had it occur three times since gamma knife. Has anyone experienced anything similar?

Yes.

I had fortification scotomas recurring after a combined angiogram and embolisation procedure. They reduced in frequency over the subsequent weeks but recurred again when I had a further angiogram.

My theory is that the scotomas are provoked by the contrast material and reduce as that is absorbed over time.

I would hope you’ll find them reducing in frequency in the same way.
